What's Wrong?

Using git worktree is broken, claude use his tooling to execute/search/bash on the 'main/master' git branch instead of the worktree branch which result in mis understanding of the real code that was changed.

What Should Happen?

claude code should be isolated only to the worktree with all the tooling.
